I'm looking at some wheels and tires for the wifey's gs. I just got the car for her and don't know much about the GS with respect to wheels and tire profiles and the like.

She's got factory 17's on it right now and I'm looking at keeping the comfort there but upgrading her to 19's.

I got a deal on some 19's that have a 'FAT' tire setup of 245-45/19 and 275-40/19. The tire calculators that I've used online have told me that this translates to a 8%+ difference in the diameter difference in both the front and rear.

The calculators also tell me that I'll run into brake failure at the tire size difference.

The car will be lowered on adjustable suspension and set to stiff so I'm not worried about rubbing or offsets here.

Will this tire size be a problem? I dont want to buy a 40 profile tire if the 45 up front will work. I also dont want her brakes failing.

As for looks -- I'd rather not here her complaining about how it looks nice but feels like crap and how the ride is too rough.

Thanks in advance.

I've done 275/35-19 on 19x10.5 +35, and it rubbed on stock quarterpanels. It was firm but comfortable compared to stretched tires, but don't expect fluff like stock ride. I highly recommend 245/35-19 up front and 275/30-19 if you don't enjoy rubbing. As long as you're not too low, you should be able to pull it off, except your speedometer will be off by roughly 5% (3% difference maximum).

It's best if you shave the rear quarterpanel and roll the front fenders if you would like a more aggressive setup. If you want a lower stance but still want more sidewall, 18"s are the way to go.
